This invention relates to improvements in valve apparatus and isdirected more particularly to improvements in cone valves and the likeand this application is a division of an application filed by me October20, 1937, Serial No. 170,000,

now Patent 2,169,525, granted Aug. 15, 1939.

According to the principal objects of the invention a cone valve isprovided which includes a body having a tapering seat or bore, a cone orplug, and novel operating means to move the plug axially between seatedand non-seated positions and rotate the same between open and closedpositions.

According to another object of the invention,

means is provided for feeding a sealing and/or lubricating medium whichis operable to supply the lubricant or sealing medium to the coactingsurfaces of the plug and valve body and journal parts not only to sealthe joints but to act as a lubricant to facilitate operation, the saidmeans being operable accordingly as the plug is moved from one position.to another.

Various other novel features and advantages of the invention will behereinafter more fully referred to in connection with the accompanyingdescription of the present preferred form of the invention referencebeing had to the accompanying drawings, wherein:

Referring now to the drawings more in detail,

the invention will be fully described.

The valve apparatus shown in Figs. 1, 2 and 60 3 includes a. body 2 anda cap 4 which may be secured together in some suitable manner as bybolts 6. The body 2 is provided with inlet and outlet ports 8 and I0which may be screw-threaded as shown for receiving, a pipe or said ports55 may be flanged or otherwise provided with con- Divided and thisapplication July 17, 1939, Serial No. 284,853

. nections for connecting the valve to a pipe line.

A valve plug l2, sometimes called a cone, is provided which ispreferably tapering and the body is provided with a tapering seatingbore to receive the said plug. A stem l4 associated with 5 the plugextends upwardly therefrom and it, as well as a part l6 associated withthe plug, may be joumalled in the cap 4 for reciprocating and rotatingmovements.

It is ordinary practice to provide a stuiiing box 10 for the stem orspindle of the plug and this may be in the form of a gland I8 disposedon the upper side of a packing 20.

The gland l8 in the form of the invention shown is urged downwardly bybolts 22, or the 15 said gland may be of the screw type if desired.

A pilot or lower journal 24 is provided on the plug l2 which has abearing in the body which together with the upper part of the plug andstem which are joumalled in the cap guide the plug 20 I for itsreciprocating and rotating movements.

The plug is movable up and down between seated and non-seated positionsin the bore and is rotatable between open and closed positions. In

operation the plug is moved upwardly from off 2 its seat, rotated andthen reseated.

a A collar 30 is rotatably disposed around the upper part of the cap 4and is held against axial movements. It may be formed of two. halvesbolted together as by bolts 32 as shown. Links 0 34 are pivoted at 36 tothe collar in any suitable way and the lower ends of the links 34 asshown .in the drawing are received in slots 3| of the .collar.

The upper end of the stem or spindle I4 is 85 threaded at 38 and collars40 and 42 are in screwthreaded engagement therewith. A yoke 44 isprovided on the spindle between the collars 40 and 42 and the yoke maybe moved up and down by the collars for locating the yoke on the spin-40 dle in various positions of adjustment. The yoke is non-rotatablerelative to the spindle and this may be accomplished by any suitablemeans such as a key in the spindle disposed in a slot of the yoke. 5

An operating member in the form of a lever having a manually engageablehandle part 52 has lugs 54 which are pivotally connected at 56 to'theyoke 44. Slots 58 in opposite sides of the operating member receive theupper ends of the links 50 34 which are pivotally connected at 60 to theoperating member.

The parts are so arranged that as the lever 50 is swung up and 'down thespindle I4 and thereby the plug I2 is raised and lowered or movedbetween seated and non-seated positions. In Fig. 1, lever 88 is in thenon-seated position of the plug. When swung. downwardly or clockwise, itis then in a position wherein the plug is seated in its bore in thebody.

A stop 82 of the operating member engages with a stop 84 of the yoke asshown to limit the movement of the lever in one direction. Another stop88 and stop 68 of the yoke engage when the operating member is in plugseated position. When the lever is swung upwardly from the positionshown in Fig. 1, it may be rotated to rotate the plug between its openand closed positions. As stated, in Fig. 1 the lever 88 is shown in anelevated or plug unseated position, and for clearness, is shown as beingmidway between open and closed positions of the plug.

The operating mechanism works with a toggle action so that the operatingmember is releasably locked in its plug seating position. Adjustment isprovided by moving the collars 48 and 42 along the spindle to move andposition the yoke. This makes it possible to adjust the parts so thatthe plug may be forced into the desired and proper seating position bymeans of the operating mechanism and any inaccuracy in machining orassembling of the parts may be easily and readily compensated for.

According to the invention it is desired to supply a sealing andlubricating medium to the coacting surfaces of the plug and bodystructure so as to prevent leakage and facilitate ease in operation andthe sealing and/or lubricating medium will be hereinafter called medium.

To that end, groove I8 is provided in the coacting surfaces of the plugand body. These are preferably around the ports 8 and I8 and connectedby a communicating groove indicated by I2. It will be understood thatthe grooves and as many as desired may be in the plug or body or both orpartly in the plug and partly in the body.

Cylinders I2 are provided which have pistons I4 reciprocable therein.The pistons may be maintained in elevated positions by springs I6interposed between the upper ends or sides of the cylinders and collarsI8 on rods 88 associated with the pistons.

A bracket or connection 82 is associated with the body and cylinders andit has passageways or ducts such as 84 and 86 in communication with thecylinders and with a passageway or passageways such as 88 in the bodyleading to at least one of the grooves I2 of the seating surfaces of thebody and cap.

The cylinders are positioned so that the rods 88 are engaged by theoperating member when it is moved to seat the plug in either the open orclosed positions of the plug. That is, when the operating member hasbeen swung horizontally toposition the plug for moving it downwardly toseated position and is swung downwardly it engages a piston rod 88 toforce it downwardly and thereby causes the piston to force the mediumwithin the cylinder through a. passageway into the grooves around theseating surfaces of the plug and body. Therefore, each time that theplug in open or closed position is moved to seated position a supply ofmedium is forced into the grooves to seal the plug thereby eliminatingleakage and supplying lubricant to facilitate ease in unseating theplug.

In addition to the grooves associated with the seating surfaces of theplug, it will be obvious that it is an easy matter to providecommunication between the one or both cylinders and the bearings for theupper and lower ended the plug so that the said bearings will receive acharge .of medium.

It will be desired, as shown in Fig. 4, to provide some means to preventthe sealing medium from being forced from one cylinder to another. Tothat end a check valve or valves may be placed in the communicatingpassageways or cylinders.

In Fig. 4 there is shown a check valve 88 which is in the form of a ballthat is urged upwardly by a spring 92. As the medium is forceddownwardly from the cylinder I2 by a piston therein, it forces the valvedownwardly soas to pass thereby. When pressure is exerted upwardlyagainst the valve by the other cylinder, it assumes its seated positionto prevent the medium being forced upwardly.

Stops 96 and 88 on the member 88 coact with stops I88 and I82 on the capso that the operating mechanism is limited in its horizontal rotationthereby to accurately position the plug in either open or closedposition.

The cylinders may be supplied with lubricant in any suitable manner asfor instance by pressure means applied to a fitting indicated by 81which as usual includes a check valve.

From the foregoing it will be observed that the plug is moved betweenseated and non-seated positions and between open and closed positions bya novel operating mechanism which is readily adjustable and that meansfor supplying a lubricating and sealing medium is operable by theoperating means.

In the foregoing the pistons are depressed to cause the medium to beforced from the cylinders but it will be possible to construct theapparatus so that upward movements of the pistons will bring aboutfeeding of the medium.

In some cases it may be desired to employ a single cylinder and pistonoperable by the operating means in its valve open and closed positions.To that end as shown in Figs. 5 and 6 the operating member II8 has partsII2 for entering a slot II4 of the piston rod IIG. With this arrangementas the operating member is moved from the neutral central position shownin Fig. 6 to the closed or open position of the plug a part -I I2 of theoperating member enters the slot I I4.

Then when the operating member is swung to move the plug verticallyofthe bore the rod 8 is reciprocated to actuate the piston and feed themedium.

As shown in Fig. 7 the invention is applicable to operating mechanismfor operating the plug. In Fig. '7 a casing is shown at I28 and a crosshead I22 is reciprocable back and forth on rods I24. A valve stem isrepresented by I 28 and a 'lever I28 is threadedly connected thereto andto the cross head I22 by a link I38. A part I82 on the cross headengages with arms I34 and I36 a member I38 fixed to the stem I26. As thecrosshead is moved back and forth the levers I28 and I38 swing back andforth so that the plug is moved up and down between seated andnon-seated positions and rotated between open and closed positions.

Cylinders I48 supported by brackets I42 on the casing I28 have pistonstherein provided with rods I44 and levers I48 having angularly disposedarms are pivoted as shown. An arm of the levers are arranged to lie inthe path of movement of a part I48 of the cross head and the other armsare arranged to act on the piston rods all as shown. As the cross headmoves between open and closed positions of the plug the levers areoperated and in turn act on the rods so that medium is fed from thecylinders which may be connected by pipes such as I50 to grooves andother parts that it is desired to supply the medium to.

While I have described the invention in great detail and with respect tothe present preferred form thereof, it is not desired to be limitedthereto since changes and modifications may be made therein withoutdeparting from the spirit and scope of the invention. The invention maybe embodied in other specific forms without departing from the essentialcharacteristics thereof. The present embodiments are therefore to beconsidered in all respects as illustrative and not restrictive, thescopeof the invention being indicated by the appended claim rather thanby the foregoing description, and all changes which come within themeaning and range of equivalency of the claim are therefore intended tobe embraced therein.

What it is desired to claim and secure by Letters Patent of the UnitedStates is:

A valve apparatus comprising in combination, a body, a plug rotatabletherein between closed and open positions and reciprocable betweenseated and non-seated positions in either open or closed positions, aspindle fixed to said plug, channel means associated with the coactingsurfaces of said body and plug, means for actuating said spindleincluding a member movable between open and closed positions of the plugand between seated and non-seated positions thereof when the .plug is ineither open or closed positions, means for supplying lubricant to saidchannels connected thereto including lubricant containers and movableactuating members therein disposed in the path of movement of theactuating means member when in either closed or open position of theplug.
